Gaara's last name

[ad4mz41]

Anyone know Gaara's last name? I don't recall them saying it at all in the anime. All I remember them calling him was Gaara of Sand/ Desert.

We do not know, no one does.

for all we know, the sand village might not even give last names to ninjas.....maybe they're all just "somebody of the something"
